Holy City Heating and Air is exceptional. I have great respect for their professionalism, communication, quality of work, and transparency. The office staff and techs work cohesively to provide quick solutions and fair prices for their clients. I’ve dealt with many HVAC companies through the years (as a retired property manager) and, by far, Holy City is the best I’ve had. They are a caring and trustworthy team of good people. I’m not flattering them- just truth w/ my experience.

Full renovation of a duplex downtown Charleston included new HVAC systems for the two floors. We opted for Daiken. The install went pretty smooth compared to my other contractors. They were neat and finished the job rapidly working in the heat of the attic as well as the din of the crawlspace.
The system however has not been without issues. We had a slow leak in one of the lines and then the system went down due to excessive humidity in the crawlspace flooding the overflow pan. The upstairs unit has trouble maintaining temperature but I have some leaky windows and no attic insulation which may be the cause. We shall see when that gets remedied.
Holy City service has been pretty.good though, addressing issues as they arise. They are usually very quick to respond and did not leave until problem was repaired. I feel confident that they will continue to support the system as it ages. I have not tested the heat portion of the unit yet, but not too worried about that.
The digital thermostat and app is nice, I can set the temp remotely as if I was standing in front of the display. It also has some diagnostics that I set up to connect to Holy City so they can monitor the system performance remotely.
Lost a star due to issues, otherwise would have been 5.

Anthony is hands down the best plumber we’ve worked with! He came out the same day we called, quickly diagnosed the issue, and had it fixed in no time. His knowledge and professionalism were impressive, and he took the time to explain everything clearly. Highly recommend!

Been meaning to share my experience with Holy City Heating and Air. My first impression was the attitude of the teammates, and how they all really liked working for Tom. From start to finish, everyone came prepared to work and got it done. Amanda immediately went to work to get the job, and tee'd it up for Brandon and the rest of the team. Marto's ductwork crew were diligent doing their part too. I barely even saw them as they were always busy getting it done. Once completed, Tom came through afterwards, got dirty, and crawled the crawlspace to ensure things were done to his standards. He really took care of me and provided a few extras at his expense. I'm very pleased with the quality of work and pride the team has for each other, and the company.

Jennifer with Holy City Heating and Air was awesome and quick to respond to my appointment request. She got me on the schedule fast and communicated with me the whole time. Alec showed up on the appointment date and was great. It was clear that he was knowledgeable about my HVAC unit and explained everything clearly and made it easy to understand. Looking forward to working with Holy City Heating and Air again in the future!
